On the other hand, the authentication process responding section 11i of the lock controller 10 creates response data from the received challenge data and the lock controller ID stored in the memory section 12 and transmits the data to the lock unit 30. The authentication processing section 31c compares the response data received from the lock controller 10 and the response data previously calculated, and judges that the lock controller 10 is a proper device when the response data coincides with the other response data.
  • Fig. 8 is a function block diagram of the control section 71. As illustrated in this figure, the control section 71 includes an ID registration process responding section 71a, and an authentication process responding section 71b as functional divisions.
  • the ID registration process responding section 71a responds to a signal received from the lock controller 10 in the portable device ID re-storing process performed by the lock controller 10. More specifically, when receiving a response requiring signal from the lock controller 10, the ID registration process responding section 71a transmits a response signal to the lock controller 10 in response to the response requiring signal. In this case, the ID registration process responding section 71a may transmit the response signal when receiving the response requiring signal, or may transmit the response signal when a predetermined signal is inputted through the operation sections 75 and 76 after receipt of the response requiring signal and execution of predetermined switch operation by the operator.
  • the authentication process responding section 71b responds to a signal received from the lock controller 10 in the authentication process performed by the lock controller 10. For example, when the authentication process method is the challenge and response method mentioned above, the authentication process responding section 71b creates response data from the challenge data received from the lock controller 10 and the portable device ID stored in the memory section 72 and transmits the response data to the lock controller 10.
  • Fig. 9 shows an example of the portable device ID re-storing process.
  • Fig. 10 shows an example of the backup data renewal process. Initially, the re-storing process is explained. It is assumed that only the portable device 70B is present within the detection range of the lock controller 10, and that the portable device 70A is absent in the detection range.
  • the ID acquisition processing section 11c transmits a requirement signal requiring the portable device IDs and the lock controller ID to the lock unit 30 (S101).
  • the ID registration process responding section 31a of the lock unit 30 having received the requirement signal reads the portable device IDs of the portable devices 70A and 70B and the lock controller ID stored in the memory section 32 as backup data, and transmits these IDs to the lock controller 10 (S102).
  • the lock controller ID storing section 11e of the lock controller 10 stores the lock controller ID acquired from the lock unit 30 in the storage section 12 (S103).
  • the portable device searching and storing section 11d selects one of the plural portable device IDs received from the lock unit 30 (portable device 70A in this case), and transmits the selected portable device ID and a response requiring signal (S104). Since the portable device 70A which is not present within the detection range as described above does not receive the response requiring signal, the lock controller 10 does not receive a response signal from the portable device 70A.
  • the portable device searching and storing section 11d selects among the plural portable device IDs received from the lock unit 30 a portable device ID (portable device ID of portable device 70B in this case) different from the portable device ID previously selected (portable device ID of portable device 70A in this case), and transmits the selected portable device ID and a response requiring signal (S105).
  • the portable device 70B since the portable device 70B is present within the detection range, the portable device 70B receives the portable device ID and the response requiring signal.
  • the registration process responding section 71a of the portable device 70B compares the received portable device ID and the portable device ID of the portable device 70B stored in the memory section 72, and transmits a response signal to the lock controller 10 after confirming that the response requiring signal has been addressed to the portable device 70B (S106).
  • the portable device searching and storing section 11d of the lock controller 10 having received the response signal reads the lock controller ID from the memory section 12, and transmits the lock controller ID to the portable device 70B (S107).
  • the portable device searching and storing section 11a may transmit the portable device ID of the portable device 70B as well as the lock controller ID.
  • the ID registration process responding section 71a of the portable device 70B may judge that the lock controller ID has been transmitted to the portable device 70B based on the portable device ID transmitted from the portable device searching and storing section 11a.
  • the ID registration process responding section 71a of the portable device 70B stores the received lock controller ID in the memory section 72 (S108), and transmits a completion notifying signal indicating this fact to the lock controller 10 (S109).
  • the portable device searching and storing section 11d stores the portable device ID of the portable device 70B in the memory section 12 (S110).
  • the portable device searching and storing section 11d may store the registration number information indicating the number of the stored portable device IDs ("1" in this example) in the memory section 12.
  • the lock unit 30 may authenticate the lock controller 10 based on manufacturer information having been stored in the memory section 12 during manufacture of the lock controller 10 to indicate that the lock controller 10 is a proper device.
  • the lock unit 30 may transmit a signal indicating this fact to the lock controller 10 and then the lock controller 10 may transmit the requirement signal in S101.
  • the backup renewal processing section 11g of the lock controller 10 transmits a requirement signal requiring transmission of the portable device information stored as backup data to the lock unit 30 when the start switch 50a is turned on by the rider, for example (S201).
  • the backup renewal process responding section 31b of the lock unit 30 transmits the portable device information stored in the memory section 32 as backup data to the lock controller 10 (S202).
  • the backup renewal processing section 11g compares the received portable device information and the portable device information stored in the memory section 12 (S203). In this example, since the portable device ID in the memory section 12 has been changed before the renewal process, the portable device ID does not coincide with the other portable device ID. Thus, the backup renewal processing section 11g transmits the portable device information in the memory section 12 to the lock unit 30 (S204).
  • the backup renewal process responding section 31b When receiving the portable device information from the lock controller 10, the backup renewal process responding section 31b overwrites the newly received portable device information on the portable device information stored in the memory section 32 to obtain new backup data (S205). In this step, the backup renewal process responding section 31b may transmit a signal indicating completion of the renewal process of the backup data to the lock controller 10.
  • Comparison between the backup data prior to renewal retained by the memory section 32 and the portable device information retained by the lock controller 10 may be performed by the lock unit 30.
  • the backup renewal processing section 11g transmits the portable device information stored in the memory section 12 to the lock unit 30 according to predetermined timing.
  • the backup renewal process responding section 31b compares the portable device information received from the lock controller 10 and the portable device information stored in the memory section 32 as backup data. When the portable device information does not coincide with the other portable device information, the newly received portable device information is overwritten on the stored portable device information.
  • Fig. 11 is a flowchart showing the flow of the processes executed by the replacement detecting section 11a and the ID registration processing section 11b.
  • Fig. 11 is a flowchart showing the flow of the processes executed by the replacement detecting section 11a and the ID registration processing section 11b.
  • the memory section 32 of the lock unit 30 retains an ID table sequentially storing a plurality of portable device IDs.
  • the replacement detecting section 11a searches the memory area of the memory section 12 to judge whether the portable device ID has been stored (S301). When it is determined that the portable device ID has been already stored, the process ends.
  • the ID acquisition processing section 11c transmits a requirement signal requiring transmission of the portable device IDs and the lock controller ID to the lock unit 30 (S302), and acquires a plurality of the portable device IDs and the lock controller ID returned from the lock unit 30 (S303).
  • the portable device IDs are stored in the ID table discussed above and transmitted in the form of the table.
  • the lock controller ID storing section 11e stores the lock controller ID in the memory section 12 (5304) .
  • the portable device searching and storing section 11d establishes parameter i as initial value 1 (S305), and transmits the portable device ID stored ith in the ID table and a response requiring signal (S306). Subsequently, the portable device searching and storing section 11d judges whether a response signal has been received from the portable device retaining the portable device ID transmitted in S306 (S307). When it is determined that the response signal has not been received yet, the portable device searching and storing section 11d judges whether predetermined time has elapsed from the time of transmission of the response requiring signal (S308). When it is determined that the predetermined time has not elapsed yet, the process returns to S107 and the portable device searching and storing section 11d again judges whether the response signal has been received.
  • the portable device searching and storing section 11d judges whether the response requiring signal has been transmitted to all the portable devices retaining the portable device IDs stored in the ID table (portable devices 70A and 70B in this example) (S309). When it is determined that the response requiring signal has been already transmitted to all the portable devices, it is judged that the portable devices 70A and 70B are not present within the detection range and the re-storing process of the portable device ID ends. In this process, the portable device searching and storing section 11d may turn on the indicator lamp 90 to notify the operator that the re-storing of the portable device ID has not been completed, for example.
  • the portable device searching and storing section 11d increments the parameter i by one (S310) and the process returns to S306. Then, the portable device searching and storing section 11d again transmits the portable device ID stored ith in the ID table and the response requiring signal.
  • the portable device searching and storing section 11d transmits the portable device ID of the portable device 70A or 70B having transmitted this response signal and a storage requiring signal requiring storage of the lock controller ID in the memory section 72 (S311). Then, the portable device searching and storing section 11d receives a completion notifying signal indicating that the lock controller ID has been stored in the memory section 72 in response to the storage requiring signal from the portable device 70A or 70B (S312) . Also, the portable device searching and storing section 11d stores the portable device ID of the portable device 70A or 70B having transmitted the response signal in the memory section 12 (S313). Then, the portable device searching and storing section 11d turns on the indicator lamp 90 in a predetermined manner to notify this fact to the operator (S314).
  • the replacement detecting section 11a of the control section 11 detects replacement of the lock controller 10 with new one.
  • the ID registration processing section 11b searches the portable device present within the predetermined detection range, and stores the portable device ID of this portable device in the memory section 12.
  • the re-registration of the portable device ID needed when the lock controller is replaced can be facilitated.
